Why is the BF indicator ON, and the LINK and ACT indicators also ON on my SMC Networks EX245-EA2?

If the BF, LINK, and ACT indicators are all ON on your SMC Networks I/O Systems, it could be due to several reasons. It might be a communication issue, so check the cable and ensure connection to the PROFINET communication. The IO Controller could be defective, so examine that as well. The device name might be incorrect, so verify the device names. Also, the GSD file might not be correct, so double-check the GSD file. Finally, the configuration data sent by the IO Controller might not match the actual layout; in this case, configure the SI unit according to the actual layout.
